How Often Should the Differential Oil of a Truck Be Changed?

[VonKatherine]

Truck differential oil should be changed every 40,000 kilometers. Changing the differential oil prevents excessive wear of the vehicle's differential gears, which could lead to differential damage. The steps for changing differential oil are as follows: 1. Lift the vehicle and place a large container underneath to catch the used oil. Use an appropriate screwdriver to remove the inner and outer shells of the transmission. 2. When most of the oil has drained, remove the last oil pan. 3. Remove the oil pan gasket and clean any surrounding stains. If the gaps are not clean enough, use tools and cotton thread to thoroughly clean all the filtered parts of the transmission oil, then reinstall them one by one. 4. Wipe the surfaces of the replacement parts clean, reinstall the cleaned oil pan and gasket, and add the original manufacturer's oil.
